SIGN-RECEPTACLE.

Specification of Letters Patent.

Patented Nov. 10, 1908.

To `all 'whom 'it may concern:

Be it known that I, CLARENCE D. BLATT,l .a citizen of the United States` ofv America,

residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Sign-Receptacles, of which the following 1s a specication.

The ain object of my invention is to 4so construct an electrical sign receptacle that while it may be set into the sign board in any position in which the direction of the wires may make most convenient,.it can be -held in the selected position securely and without danger of its being worked loose by i vibration.

In the accompanying drawings' Figure 1v *of the receptacle and sign board, when separated;l Fig. 2 is a view, partly in section showing the receptacle about to be secured in place; Fig. 3 is a sectional view taken in a plane perpendicular to the section, Fig. 2, but With the parts secured; and Fig. 4 is a rear view of the receptacle before the insulating and waterproofing compounds have been applied.

. A is the metallic sign plate having holes such as a in itat intervals, according to the number Aand arrangement of the electric lamps required for the particular case.

The receptacle for the electric lamp is somewhat similar to a style of sign receptacle now in common use in that it has an insulating body part B, containing the lamp receiving terminals, one of which is the usual screw shell b, to be passed through the hole a in the sign plate from the rear,

the receptacle to be held to the board by an insulating screw ring R screwed onto the ring B from the front of the plate A. The

' body part B may have' a neck 71. of adiameter to fit neatly within the hole a in the plate. Heretofore this shoulder has had on it at a suitable point a radial projection to enter a notch a in the plate to prevent the rotationv of the receptacle. That projection is liable to be broken ofi', and in any case, it permits the receptacle to be secured in only one position rotarily, which may be inconvenient with respect to the running of the wires from the back of one receptacle to adjacent ones. To overcome these diiiiculties and at*y the same time to secure the receptacle to the plate so that the screw ring R will not work loose from vibration, I provide a locking ring D which is adapted to t around the neck /L back of the sign plate. This ring is provided with a projection d to lit into the notch al in the sign plate, and this projection may be punched upwardly out of the ring itself as shown. The ring is also provided with one onmore projections d1 to engage any one or more of a large number of recesses b1 on the body of the receptacle, and preferably I form the projections Z1 by making two diametrically opposite indentations downwardly. in the ring, and a large number of corresponding recesses on the upper face or shoulder of the body B around .the .neck l1. to receive the projections d1. I also bend the ring D out of its natural plane, as shown in Figs. l and 2, and I make it of elastic metal so that when the parts shown in Fig. l, are put together as indicated in Figs. 2 and 3, and the screw ring R is screwed down, not only will the ring D serve to lock the receptacle securely to the sign plate in any desired position convenient for the running of the wires, but the ring D will act as a spring washer to prevent the ring R from jarring loose by vibrations to which l the sign plate may be subjected.

The respective vlamp-receiving terminals are connected in any usual way to terminal plates P and P1 lying in a central recess y? and projecting into grooves p1 for the wires at the back of the receptacle, Fig.r 4. rIhe -central recess is to be lilled with insulating -compound as usual, and waterprooling compound is poured into the grooves p1, to cover up the bared portions of the wires after they have been connected up to the binding iscrews on the terminal plates.

I claim as my invention:

1. A sign lamp receptacle consisting of a body part' carrying -lamp-receiving terminals and an attaching screw ring, with a locking' receptacle rotarily to the plate, said locking ring being elastic and bent and adapted to bxle interposed between the receptacle and ate. p 4. A sign lamp receptacle, consisting of a body part having on its face a number of recesses, a screw ring to attach the receptacle to the sign plate, .and a locking ring hav ing a part to en age the si plate and also projections on t e undersix1 of the ring to engage any of the recesses 'in said body part. 5. .A sign lamp receptacle, consisting of a body part and a ring to attach 'it to the sign plate, in combination with means to lock the receptacle to the sign plate in any of many 15 positions rotarily.

plate, in combination with means to lock the receptacle to the sign plate in any one 0f 20 m-any positions rot-arily.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
